I am interested in hooking up a device only to an optical input and don't forsee ever having to use the front panel inputs. I would therefor like to associate the device with input "VID 5" and assign one of the optical inputs to that. At the bottom of page 5, column 1, it says that any digital input can be used for any source device, but the connection record chart on page 19 does not contain a block for "VIDEO 5", suggesting otherwise. Turning to the front panel illustration on page 7 for guidance, items 18 through 22 refer to a page TK. There is no such page in the manual, nor was there a loose page in the packaging.
